Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Urban planning issue

[–] Donebrach@lemmy.world 3 points 8 months ago* (last edited 8 months ago) (1 children)

No amount of urban planning can solve a 300 year old city built in a 10,000 year old hilly mess of a glacial valley.

ebikes with regenerative braking could do very well in that environment. Try taking a look at what's within 15 minutes by bike

I know what’s 15 minutes away by bike because I bike everywhere I go. Doesn’t change the fact that I am sick of it.

Walk a bit. Take a bus. Buy an electric scooter. Move. All decent options

Busses barely provide any service where I live. Walking is useless because nothing is close enough for that to be a viable option. I have an electric scooter, it is useless because of the local terrain (and is just as shitty as biking as a means of transport anyway). And sure, yeah, just “move” because that is so simple to do.
